PEN.

Specification of Letters Patent.

Application filed January 29, 1909. Serial No. 474,919.

To all whom it may concern:

Be it known that I, HERBERT lV. KUEFF- man, a citizen of the UnitedStates, residing at Burlington, in the county of Alamance and State ofNorth Carolina, have invented new and useful Improvements in Pens, ofwhich the followin is a specification.

My invention r ates to improvements in ruling pens.

The primary object of the invention is the provision of a (pen of thischaracter which shall be provi ed with a reservoir from which the inkshall flow on to the inner sides of the nibs of the pen and with a valveby means of which tie flow of ink to the pen nibs 'can be controlled.

A further object of the invention is the provision of a fountain rulingpen with means by which the ink in the reservoir may be kept underressure at all times.

A still furtier object of the invention is the rovision of a fountainrulin pen which shal be simple, durable and eiiicient, and which may bemanufactured and sold at a comparativel low cost.

With the a ove and other objects in view, the invention consists in thenovel construction, combination, and arrangement of parts hereinafterfully described and claimed, and illustrated in the accompanyingdrawing, wherein Figure 1 is a view in side elevation of a fountainruling pen constructed in accordance with my invention. Fig. 2 is a topplan view thereof. Fig. 3 is a sectional view taken on a plane extendingcentrally and longitudinally through the pen. Fig. 4 is a detail view inside elevation of the valve of the pen. Fig. 5 is a sectional view takenon the horizontal lane indicated by the line 55 of Fig. 1, 100 ring inthe direction indicated by the arrow.

Referring to the drawing by reference numerals, 1 designates the body ofm improved fountain ruling pen. A air 0 relatively spaced nibs 2 areforme integrally with and project from one end of the body 1. Theopposite end of the body 1 is provided with a circular socket 3 WlllChhas the inner side of its annular wall 4 screwthreaded. The body 1 isprovided with an annular o ening 5 which opens at its ends out throngthe ends of the body, the wall of said openin being screw-threaded. Thenibs 2 may. relatively ad'usted and retained in adjusted positions ymeans of a set-screw 6 which is provided with a milled operating head 6and which passes freely through one of the nibs and threadedly engagesthe other. The handle 7 of the pen is of hollow cylindrical formation,one end thereof bein closed while the other end thereof is fu ly open.At its 0 en end the handle 7 is provided with a re uced stud 8 which isexternally threaded for engagement with the threaded wall 4 of thesocket 3, said stud detachably securing the handle tothe body 1. Aflexible reservoir 9 also of cylindrical formation, is removably mountedin the handle 7, one end of the reservoir being closed while the otherend thereof is fully open. The open end of the reservoir 9 1s secured tothe stud 8 by means of a hollow bushing 10, the bushing clamping the endof.the reservoir between its outer inclined side and the inner inclinedside of the stud.

The free end of the reservoir is also clamped between the end of thestud 8 and the bottom wall of the recess 3. The opening in the bushing10 registers with the opening 5' in the body 1.

The ink is conveyed from the reservoir 9 on to the inner sides of thenibs 2 by means of a rigid feed tube ll'which is located between thenibs and which is provided with a reduced discharge end 12 having itsdischarge openin 13 located in close proximity to the ends 0 the nibs.The opposite end of the feed tube has threaded engagement with theopening 5 of the body 1, and the discharge end 12 is detachably securedto one of the nibs 2 by means of a lug 14 fitting in a lug 15 formed onthe inner side of said nib. The discharge of the ink from the tube 11 onto the nibs 2 is under the control of a valve 16 which comprises a fiatbody 17 which is slidably mounted in openings 18 formed in the feed tubeand in an opening 19 formed in one of the nibs 2, the thickness of thefeed tube being increased about one of the openings 18. The valve 16also comprises a stem 20 which passes through an opening 21 formed inthe other nib 2, and a head 22 which is mounted in a socket 23 formed inand opening out through the inner side of said nib. The valve 16 isprovided at a point adjacent one of the ends of its body 17 with anopening 24 which when it registers with the passa e of the tube 11allows ink to flow on to the nibs 2. When the opening is in thisposition the valve is opened. The opening 24 is Patented Apr. 5, 1910.

normally retained out of registration with the passage of the feed tube11, that is to say, the valve is normally retained closed by means of anexpansiblecoiled spring 25 which is mounted in a casing 25. The casinghas one end fully open for the reception of the head 22 of the valvestem v20, the spring being located between the closed end of the casingand the head.. The casing 25 is suitably secured in the socket 23 of oneof the pen nibs 2. When the valve 16 is closed the stem 20 projectsabove the nib 2 through which it passes whereby to enable it to beengaged when it is desired to open the valve. The valve is arranged insuch relation to the set-screw 6 that the stem 20 is within convenientreach.

The ink in the reservoir maybe retained under pressure at all times toinsure itsproper feed to the nibs 2, through the medium of a pressureplate 26 which is located in the handle 7 outside of the reservoir andwhich is carried by and under the control of a feed-screw 27. Thefeed-screw 27 has threaded engagement with the handle 7 and it isprovided with a milled operating head 28. The several parts of myimproved fountain pen may be made of any suitable materials and theweights of the parts are such that the pen is well balanced.

It should be apparent from the above description, taken in connectionwith the accompanying drawing, that I provide a fountain ruling penwhich is simple, durable and eflicient, and which may be manufacturedand sold at a comparatively low ,cost. It should also be apparent that abody carrying an ordinary writing nib may be substituted for the body 1which carries ruling nibs 2.

While I have described the method of operation of the invention,together with the apparatus which I now consider to be the bestembodiment-thereof, I desire to have it understood that the apparatusshown is merely illustrative and that such changes may be made whendesired as are within the scope of the claims.

Having thus described the invention, what is claimed as new is 1. A pencomprising a body, nibs projecting from one side of the body, areservoir secured to the opposite side of the body, a feed tube locatedbetween the nibs and communicating with the reservoir, a valve'slidablymounted in the feed tube, said valve being provided with a stem passingthrough one of the nibs, and a spring adapted to retain the valvenormally closed.

2. A pen comprising a body, nibsprojecting from one side of the body, aset-screw carried by the nibs, a reservoir secured to the opposite sideof.the body, a feed tube located between the nibs and communicating withthe reservoir, a valve slidably mounted in the feed tube, said valvebeing provided with a stem passing through one of the nibs at a pointadjacent the operating head of said screw, and a spring adapted toretain the valve normall closed.

3. A pen comprising a body, nibsprojecting from' one side of the body, areservoir secured to the oppositeside of the body, a feed tube locatedbetween the nibs and communicating with the reservoir, a valve slidablymounted in the feed tube and provided with a stem passing through one ofthe nibs, a casing secured to the nib through which the stem passes, thestem passing through said casing, a head secured to the stem, and anexpansible coiled spring mounted between the head and one wall of thecasingand adapted to normally retain the valve closed.

4:. A pen comprising a body, nibs projecting from one end of the body,the opposite end of the body being provided with a circular-sockethaving its annular wall screw threaded, the body being provided with apassage opening at its ends out through the
